Aromatherapy—the use of fragrant essential oils to soothe, heal, and invigorate the mind and body—dates back as early as 4500 B.C. A mysterious blend of the ethereal and substantial, essential oils influence both our physical and spiritual well-being. The refreshing scent of eucalyptus clears the mind of tired thoughts. A compress of cypress, pine, or juniper eases the pain of arthritis. A rose oil massage dispels anxiety and restores a tranquil frame of mind. A drop of orange essence near our pillow sends us gently off to sleep. This complete guide to the art of aromatherapy explains how essential oils work, and describes the many ways you can use them—from baths, massages, and room fragrances to poultices, gargles, and rubs. One index covers more than forty essential oils, their uses and healing properties. A second lists more than eighty common ailments and how to use essential oils to treat them. Here is all the information you need to practice natural, holistic aromatherapy at home.
